Struct efuse::Fuse

pub struct Fuse { /* fields omitted */ }

Software fuse, with custom initial state.

Default constructor uses false as the initial state.

Methods

impl Fuse

pub fn new(initial_state: bool) -> Self

Return a new fuse with the given initial state.

pub fn initial_state(&self) -> bool

Return the initial state of this fuse.

pub fn as_bool(&self) -> bool

Return current fuse value as a boolean.

pub fn zap(&mut self) -> bool

Zap this fuse (unconditionally), toggling its value permanently.

It returns the new value of this fuse.

pub fn zap_once(&mut self) -> Result<bool, AlreadyZappedError>

Zap this fuse (conditionally), toggling its value permanently.

If the fuse was already previously zapped, it returns an AlreadyZappedError error. Otherwise, it returns the new value of this fuse.

pub fn is_zapped(&self) -> bool

Whether this fuse has already been zapped.
